1 33 PCs with significant temporal expression coefficient correlation (ecc) resulting from the two scans in the seven individuals are shown. 2 Regional correlation coefficients (rccs) included in the computation of the mean images are in bold. PC: principal component; MCI: mean component image; *: PC with marginally significant ecc, introduced in the calculation because of the very high within subject rcc (0.78).
